Definitions
- the invention relates to plants for the production of aluminum by igneous electrolysis according to the Hall-Héroult process. It relates more particularly to the handling devices used in said factories.
- Aluminum metal is produced industrially by igneous electrolysis, namely by electrolysis of alumina in solution in a bath of molten cryolite, called electrolyte bath, according to the well-known Hall-Héroult process.
- the electrolyte bath is contained in cells, called “electrolysis cells", comprising a steel box, which is coated internally with refractory and / or insulating materials, and a cathode assembly located at the bottom of the cell.
- Anodes typically made of carbonaceous material, are partially immersed in the electrolyte bath.
- the assembly formed by an electrolysis tank, its anodes and the electrolyte bath is called an electrolysis cell.
- the anodes are provided with a metal rod intended for the electrical and mechanical connection to a metal frame, called an anode frame, which is movable relative to a fixed gantry placed above the electrolysis tank.
- the anode rods are connected to the anode frame using hooks arranged on either side of the anode rods and removable connectors able to be placed on these hooks and to press the anode rods against the anode frame .
- French patent FR 2 039 543 (corresponding to American patent US 3 627 670) describes such devices.
- an electrolysis plant requires work on the electrolysis cells, including the replacement of used anodes. by new anodes.
- the most modern factories are equipped with at least one lifting and handling unit comprising an overhead crane, which can be translated above and along the electrolysis cells, and a cart equipped with several handling and intervention devices (often called "tools").
- French patent FR 2 039 543 describes a handling member intended for handling the connectors, in particular their installation, their removal and their transport.
- the Applicant has therefore sought bodies for handling anode connectors, intended for the industry of aluminum production by igneous electrolysis, which make it possible to avoid these drawbacks while remaining reliable, simple and of reduced bulk.
- the subject of the invention is a handling member intended in particular for installing and removing an electrolytic cell anode connector.

- a clamping member such as a key
- the Applicant had the idea of providing the handling member with a blocking system intended to fix the connector in the handling member in a normal handling position and with a movable member intended to act as a possible support in failure of the blocking in the handling device. Such failure can occur, for example, when the connector has been damaged or deformed or when it is worn.
- the invention also relates to an anode connector provided with a gripping means capable of cooperating with the locking system of the handling member.
- the invention also relates to a lifting and handling unit comprising at least one handling member for anode connectors according to the invention.
- the invention also relates to the use of the handling member according to the invention in a factory for the production of aluminum by igneous electrolysis.
- the invention also relates to the use of a connector according to the invention in a factory for the production of aluminum by igneous electrolysis.
- the invention also relates to the use of a lifting and handling unit according to the invention in a factory for the production of aluminum by igneous electrolysis.
- the invention will be better understood with the aid of the detailed description of preferred embodiments thereof which are set out below and which are illustrated with the aid of the appended figures.
- the invention makes it possible to avoid untimely drops of a connector during its handling. It has the advantage of requiring a limited number of mobile elements, which increases the reliability of the handling device.
- FIG. 1 illustrates a typical electrolysis cell, seen in perspective, intended for the production of aluminum.
- FIG. 2 illustrates, seen in cross section, a typical electrolysis room intended for the production of aluminum.
- FIG. 3 illustrates, in perspective view, an anode connector according to the invention and hooks for fixing said connector.
- Figure 4 illustrates, in side view, a handling member according to the invention.
- FIGS 5 and 6 illustrate the operation of the handling member of an anode connector according to the invention.
- FIG. 7 illustrates a device for unlocking the handling member.
- the electrolysis factories intended for the production of aluminum comprise one or more electrolysis rooms (100) comprising a large number of electrolysis cells (1) normally arranged in rows or rows (typically side by side or head to head ), each row or file typically comprising one or more hundreds of cells.

- the lateral pins (212, 212 ') generally form the common axis (213) and are typically constituted by the ends of a rod - generally cylindrical - which passes through the connector from side to side. Said pins (212, 212 ') are intended to rest in the recess (11, 11') of the hooks (10, 10 ') fixed to the anode frame (5) and located on either side of each anode rod (9).
- a connector (200) has at least a first state, called a tight state, and a second state, called a loose state.
- the tightening state allows either to fix the anode rod (9) on the anode frame (5), or to release the anode rod (9): in the tightened state, the connector (200) applies pressure against the anode rod (9) and the plate on the anode frame (5); in the loose state, the connector (200) no longer applies pressure against the anode rod (9), so that the connector and the anode can be removed.
- a connector (200) can pass between the two tightening states by actuation of the tightening means (205, 206, 210, 211).
- These means normally include a screw (210) capable of cooperating with an external tightening member (302), such as a key, generally fixed to a handling member (300).
- the clamping screw (210) is typically provided with a head (211) capable of being inserted in the clamping member (302) for tightening or loosening the connector (200).
- the clamping means also comprise nuts (205, 206) fixed to the levers (201, 202) of the connector, preferably in a movable manner, and capable of cooperating with the screw (210) of so as to allow the articulation of the levers (201, 202) and the tightening / loosening of the connector (200).
- the levers (201, 202) of a connector (200) generally comprise crosspieces (203, 204) intended in particular to communicate, directly or indirectly, the clamping pressure of the connector against the anode rods.
- the electrolysis rooms (100) normally include at least one lifting and handling unit or "service machine” (20).
- Said unit (20) typically comprises an overhead crane (21) able to be moved along the electrolysis cells on raceways (23, 23 '), a carriage (22) able to move over the overhead crane ( 21), and handling and intervention devices (often called “tools”), such as a handling device (300) for the anode connectors (200).

- the handling member (300) typically comprises a frame (301) and a fixing means (304).
- the handling member (300) of an anode connector (200) provided with two lateral pins (212, 212 ') and a clamping screw (210), said connector being able to cooperate with fixing hooks (10, 10 ') of a cell (1) for the production of aluminum by igneous electrolysis so as to allow the connection of anodes (8) on said cell, said handling member comprising a member tightening (302) able to cooperate with the tightening screw (210) so as to modify the tightening state of the connector (200), is characterized in that it comprises a locking system (310, 310 ', 320 ) able to cooperate with the clamping member (302) and the connector (200) so as to lock the latter in a determined position in the handling member (300) by loosening the connector (200) using the clamping member (302), in that it further comprises at least one movable member (312, 312 ') having a first position, called position o open, and a second position, called the closed position, and in that the
- the connector In said determined position, called normal handling position, the connector is correctly anchored in the handling member, except in the event of damage, and can be moved and transported.
- the support (313, 313 ') In this position, the support (313, 313 ') is normally not necessary to carry the connector, that is to say that said support is only intended to carry the connector in the event of damage.
- the clamping screw (210) in the determined position, normally remains engaged in the clamping member (302). The connector (200) can then be disengaged or removed from said position determined by tightening the connector using the clamping member (302).
- said support (313, 313 ') is able to support the connector (200) by said lateral pins (212, 212'), when the or each movable member (312, 312 ') is in the closed position.
- the support (313, 313 ') advantageously comprises a concavity (314, 314'), essentially turned downwards in use, capable of receiving a pin (212, 212 ') of connector.
- the or each movable member (312, 312 ') further comprises locking means (314, 314') to prevent the displacement of the or each movable member (312, 312 ') from the closed position to the open position when the connector (200) rests on the support (313, 313 ').
- locking means 314, 314'
- This situation can occur when the connector is not locked - or not correctly locked - in the normal handling position, in which case the connector can be pulled down by gravity until it rests on the support (313, 313 ' ).
- This situation can also occur when the connector is released from the normal position during handling, typically following a false maneuver.
- This variant makes it possible to prevent an operator from trying to put in place an improperly fixed connector in the handling member, which could cause the connector to fall.
- the handling member is characterized in that it comprises two mobile members (312, 312 ') each comprising a support (313, 313'), in that each support (313, 313 ') comprises at least one concavity (314, 314') capable of receiving a lateral pin (212, 212 ') and in that, so as to form said locking means, the dimensions of each concavity (314, 314 ') are such that, when the connector is locked in said determined position (called normal), each movable member (312, 312') can move without hindrance, whereas, when the lateral pins (212, 212 ') of the connector (200) rest in said concavities (314, 314'), the movement of the or each movable member (312, 312 ') is mechanically prohibited by a stop effect.
- the or each movable member (312, 312 ') is typically able to be moved by pivoting about an axis (303).
- the locking system (310, 310 ', 320) comprises at least one hooking means (320) capable of cooperating with the connector (200) and the clamping member ( 302) so as to cause the connector (200) to be blocked in the handling member (300).
- the attachment means (320) is typically able to cooperate with the connector (200) by means of a gripping means (231, 232) provided on the connector.
- the hooking means (320) fixes the connector in the handling member when the connector (200) is released.
- the hooking means (320) is housed in a gripping means (231, 232) of the connector (200) during the loosening operation of the latter using the clamping member (302).
- the connector (200) can move neither vertically (because in particular of the hooking means (320) which supports the connector), nor horizontally (because of the screw (210) which remains engaged in the clamping member (302)).
- the hooking means (320) is advantageously a part, fixed or mobile, able to cooperate with the connector (200), typically by insertion into a gripping means (231, 232) provided on the connector, so as to block it .
- the attachment means (320) is typically a lug, a finger or a protuberance.
- the blocking system (310, 310 ', 320) comprises at least one guide means (310, 310'), which can be fixed or mobile, intended to guide the insertion of the connector in the blocking system.
- the guide means (310, 310 ') typically includes a fork.
- Said system preferably comprises two forks (310, 310 ') arranged so as to allow the insertion of the connector between them and the guiding of each pin (212, 212') of the connector by each fork (310, 310 '). This variant facilitates the positioning and blocking of the connector in the determined position.
- the shape of the concavity (311, 311 ') of each fork (310, 310') is advantageously complementary to that of a pin (212, 212 ') of the connector.
- the bottom of the concavity (311, 311 ') optionally makes it possible to limit the vertical displacements of the connector.
- the or each guide means (310, 310 ') is advantageously mobile. It may possibly be provided with an elastic return means capable of bringing it back into a position of equilibrium.
- the mobility of the guide means or means gives the blocking system a certain flexibility during the insertion of a connector into the handling member and thus avoids possible degradation of the elements of said system. It also makes it possible to overcome certain differences in dimension of the connectors.
- the possible concavities (311, 311 ', 314, 314') advantageously form an opening (305, 305 ') capable of preventing the transverse outlet of a pin (212, 212') of the connector.
- Said means (315, 315 ') for causing the displacement of the or each movable member (312, 312') from the closed position to the open position advantageously comprises a cam arranged on said movable member and configured in such a way that it can cooperate with said hooks (10, 10 ') - and more precisely with the ends (12, 12') of said hooks - so as to cause the displacement of or each movable member (312, 312 ') from the closed position to the open position by a relative movement between the handling member (300) and the fixing hooks (10, 10 ').
- the simplicity of this embodiment gives great reliability to the handling device.
- the means (315, 315 ') can optionally be a mechanical, pneumatic or electromechanical means controlled.
- a connector (200) particularly advantageous for implementing the invention comprises two levers (201, 202), two lateral pins (212, 212 '), a clamping screw (210), and in addition at least one gripping means (231, 232) able to cooperate with the locking system (310, 310 ', 320) of the handling member so as to lock the connector in the determined position, called the normal handling position.
- the two levers (201, 202) each comprise a cross member (203, 204) and said gripping means is a flange (231, 232) provided on at least one of the cross members (203 , 204).
- This connector (200) is capable of being handled by the handling member (300) according to the invention.
- FIGS. 5 and 6 relate to a preferred embodiment of the invention in which the handling member comprises two forks (310, 310 ') and two movable members (312, 312') provided with a cam (315, 315 ') and able to pivot around an axis (303).
- FIG. 5 corresponds to the normal case in which the connector (200) fits correctly in the handling member.
- the connector (200) is initially inserted into the hooks (10, 10 ') and resting on an anode rod (9) in the tightened state (FIG. 5 (A)).
- the handling member (300) is brought closer to the connection so as to insert the connector (200) and the hooks (10, 10 ') between the movable members (312, 312 ').
- the cams (315, 315 ') then slide over the ends (12, 12') of the hooks and cause the movable members (312, 312 ') to pivot, which then switch to the open position.
- the screw head (211) is inserted into the clamping member (302) and the pins (212, 212 ') of the connector are engaged in the forks (310, 310') ( Figure 5 (B)).
- the connector is then loosened using the clamping member, which causes the attachment means (320) to be inserted into the connector and the latter to be locked in a normal position inside the connector.
- handling unit Figure 5 (C)
- the handling member is then lifted, which causes the movable members (312, 312 ') to pivot under the effect of gravitation, which then return to the closed position ( Figure 5 (D)).
- the movable members can be moved in a way, so that, if one wishes to install the connector on another anode, one can simply carry out the procedure in reverse.
- FIG. 6 corresponds to a case in which the connector (200) is not correctly inserted in the handling member.
- the attachment means (320) is not inserted into the gripping means (231, 232) of the connector, so that the latter is not locked in the normal handling position.
- the pins (212, 212 ') then come to bear, by gravity, on the support (313, 313') of each movable member (312, 312 ') ( Figure 6 (A)). In this position, the concavities (314, 314 ') prohibit the movement of the mobile members (312, 312').
- FIG. 7 illustrates an unlocking device (400) capable of unlocking the handling member when the connector is not inserted in the normal position inside the handling member.
- Said device (400) comprises a receptacle (401) capable of supporting the connector (200) and a lever (402) capable of pivoting about an axis (403).
- the lever (402) is initially offset so as to release the sides of the receptacle (see the arrow in FIG. 7 (A)).
- the handling device (300) in which a connector (200) is inserted outside the normal position is approached to the device (400) so as to put the connector in the receptacle (401) (FIG. 7 (A)).
- Pressure is then exerted on the connector until the movable members (312, 312 ') can be pivoted without hindrance into the open position under the action of the lever (402) on the cams (315, 315') ( Figure 7 (B)).
- the handling device can finally be lifted freely, leaving the connector in the receptacle ( Figure 7 (C)).
